Application filed March 15, 1905. Serial No. 250,194.

To all whom it may concern:

Be it known that I, GEORGE F. GREENE, a citizen of the United States,residing at Detroit, county of WVayne, State of Michigan, have inventeda certain new and useful Improvement in Concrete or Cement Posts orAnalogous Structures, of which the following is a specification,reference being bad to the accompanying drawings, which form a part ofthis specification.

My invention relates to a concrete or cement structure provided with anailing-strip, the same being more especially designed for a fence-post,a railway-tie, a house-block, and for similar uses.

My invention consists of the structure hereinafter described andclaimed, and illustrated in the accompanying drawings, in Which Figure 1is a view in sideelevation of a fence-post embodying my invention,showing its adaptation to one style of fence. Fig. 2 is a similar viewshowing the adaptation of the post to a wire fence. Fig. 3 is a similarview showing the adaptation of the structure for a picket fence. Fig. 4shows in perspective a corner fence-post. Fig. 5 is a view in verticalsection. Fig. 6 is a view in cross-section, showing a modification. Fig.7 is a view in perspective of a house-block. Fig. 8 is asection on theline 8 8, Fig. 7. Fig. 9 is a view in perspective of a railway-tieembodying my invention.

The aim of my invention is to provide a structure of this class whereinthe nailingstrip may readily be applied to a cement or concrete body andbe securely held in position, the nailing-strip being readily removableand renewable should occasion require, doing away with the necessity ofdiscarding the cement or concrete body when the nailingstrip gives out,as in other structures of this class heretofore employed.

In carrying out my invention a concrete or cement body ais formed, thesame being molded of desired shape and size in a wellknown manner andfor the particular purpose.

intended. The body of the cement or concrete structure may be formed inany wellknown or desired manner, except as hereinafter described, thesame being preferably formed in molding with suitable bolt-orificestherethrough, as indicated at b. To the body of the structure so formedI secure one or more nailing-strips, (indicated at 0,) saidnailing-strips being held in place by bolts 0Z passed through the bodyof the structure and through the nailing-strips, as shown, the boltsbeing preferably formed with a head 6 at one end thereof and with anutf' at the opposite end thereof. Over the nailing-strip I locateaclamping device, (indicated at g,)said clamping'device being formed ofmetalas of sheet metal, for exampleand provided with flanges at itsextremities, as indicated at it, to project over the sides of thenailing-strip, the nailing-strip being clamped within the body andflanges of said device, whereby the nailing-strip will be effectuallyprevented from splitting. The clamping device is held in place by thecorresponding bolt passed therethrough.

Where the nailing-strips are desired to be made narrower than theadjacent face of the concrete or cement body, the flanges of theclamping device would simply extend over thelateral edges of thenailing-strip. Where, however. the nailing-strip was of a width equal tothat of the corresponding face of the body structure, the flanges of theclamping device would preferably be of sufficientlength to project overand upon the corresponding faces of the body, as indicated in Fig. 6.The nailing-strip may extend longitudinally of the concrete or cementbody or transversely thereof, as may be required. In Fig. 3 thenailing-strips 0 extend across the fence-post at the top and the bottomthereof, the clamping devicesor metal clips extending longitudinally ofthe body. To prevent splitting of the nailing-strips, the clampingdevice should of course extend crosswise of the grain of the wood of thenailing-strip.

In the formation of a fence-post I prefer to construct the body of thepost with a projecting cap, (indicated at a) the cap projecting over theupper end of the nailing-strip to protect the adjacent end of the stripfrom the weather.

The clamping devices g obviously serve as braces to materiallystrengthen the nailingstrips and their engagement upon the concrete orcement body.

The nailing-strips are made of suitable wood of desired length and widthand thickness to serve the particular purpose for which the structure isintended to be used, the nailing-strip being designed to be suitable forfastening securely thereto fencing of different kinds when the structureis designed for a fence-post, or building material where the structureis designed to be used as a houseblock, or railway-rails where thestructure is IIC designed to be used for a railway-tie. Obviously thenailing-strip may be removed, repaired, and replaced at any time withoutinury to the concrete or cement body.

The clamping devices extending across the face of the nailing-strips andover the lateral edges thereof will not only prevent splitting by strainthereupon, but will also prevent warping of the strip.

I prefer to strengthen the cement body by suitable iron rods embedded inthe plastic material in the formation of the structure, as shown at WhatI claim as my invention is 1. A concrete, cement or analogous structurehaving in combination therewith a perforated nailing-strip located uponone of the outer faces of the structure, a clamping device having aperforated body to engage the face of the nailing-strip and providedwith flanges at the extremities of the body thereof projecting over thelateral edges of the nailing-strip, and a bolt separable from theclamping device passed through the perforated naiiing-strip, and theperforated body of the clamping device and engaged with the cementstructure to secure the clamping device and nailing-strip to saidstructure.

2. In combination a concrete, cement or analogous structure a perforatednailingstrip upon one face thereof, a clamping device formed of sheetmetal having a perforated body to extend crosswise over the face ,of thestrip and provided with flanges at the extremity of the body thereof, abolt separable from the clamping device and passed through theperforated body of the device and perforated nailingstrip and engagedwith the cement structure to hold the nailingstrip in place, saidclamping device provided with flanges at the extremities of said bodyprojecting over the lateral edges of the nailing-strip for the purposedescribed, horizontal fence-wires, and staples driveninto the outer faceof said nailing-strip to hold the wires in place.

3. In combination a concrete, cement or analogous structure, aperforated nailingstrip upon one face thereof, a clamping device havingflanges at its extremities to extend crosswise over the face and. overthe lateral edges of the strip, and a bolt separable from theclampingdcvice passed through the clamping device and engaged with saidstructure to hold the nailing-strip in place, said structure providedwith an integral cap toward the upper end thereof projecting over theupper end of the nailing-strip, and over the corresponding face of thebody of the structure.

I. A concrete, cement, or analogous structure provided with anailing-strip secured upon one face of the structure, and extendingacross the full width of said structure, a flanged clamping device toengage across the face of the nailing-strip, and a bolt separable fromthe clamping device and passed through the clamping device and throughthe post to secure the clamping device and nailing-strip to the body ofthe structure, the flanges of the clamping device projecting over thelateral edges of the nailing-strip and upon the lateral surfaces of thecement structure.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
